What are some advance concepts with Velocity?

I am looking at the documentation of velocity, and it seems very straightforward.

i.e. something that one can pickup in 2 hours

Am I missing something?

What are the more advanced concepts 开发者_运维知识库with Velocity?

Any major quirks?

Apache Velocity is open source. If you want to know more about it than what the doc explains, you need to read its source or the source of things that use it. Or the many other velocity-related questions here on SO.

I think (at least for myself) there's a difference between "reading" about something and "using" that thing :).

Apache Velocity however is really that easy (and despite it's limitations) the main reason it's used in so many projects, e.g. where even non-programmers need to edit/modify template code.

If you have a smart editor with support for Velocity, than writing those templates is even easier and faster :).
